To all whom it may concern:

Be it known that I, LEOPOLDOSCONFIETTI,

a subject. of the King of Italy, residing at Legnano, in the Kingdom of Italy, have invented certain new and useful Improvements in Shuttle-Guards for Looms, of which the following is a specification. 1

The invention has been patented in Italy,- Vol.7l, No.473,July 13,1894; in Germany, No. 85,206, November 3, 1894; in Great Britain, No. 20,533, October 26, 1894; in Austria,Vol. 44, Fol. 6,573, December 31, 1894; in France, No. 242,409, October 26, 1894; in Belgium, No. 114,196, February 21, 1895; in Switzerland, No. 9,337, September 27, 1894, and in Spain, No. 16,708, February 6, 1895.

This invention relates to an improved shuttle-guard for looms, fulfilling the following conditions: First, the operator is in no way interfered with in manipulating the shuttles or in handling the threads; second, the lay and the warp-threads are but little covered or hidden by the said guide or guard when it is in its protective'position and not at all whenit is turned back; third, the warp-threads are in no way damaged by the operation of the said device, and, fourth, the shuttle deviating from its course is not arrested in its mo tion, but is brought back to its proper course or race.

This improved shuttle guiding or guard apparatus or device mainly consists of a number of arms pivoted to the cover of the batten or lay, the distance between which arms is less than half the length of the shuttle and which in their turned-down position are situated so close over the shuttle-race that the shuttle, before it can leave the warp-threads, is compelled to meet a guiding-arm and by it be conducted back to its proper course. When the arms are turned up for the attachment of a warp-thread or any other manipulation which the loom may require to be performed, it is not necessary first to secure them in position by means of a pin or bolt or the like, as they of their own accord will remain in the desired position until they are turned down again by the attendant.

A guide or guard of this class is represented in the accompanying drawings, in which v v Figure 1 is a transverse sectional View showing the lay or batten with the guide and the Warp-threads open. Fig. 2 is a similar view, but showing the Warp-threads closed at the moment when the lay catches or secures the weft-thread; and Fig. 3 is a front view of the lay provided with'the improved device. Figs.

4 to 6 illustrate a modified form of apparatus in which the guiding-arms assume a closed .60 appearance or shape. The effect of this arrangement, however, is exactly the same as that of the first-mentioned construction.

Upon the cover A of the lay the rail 1), provided with the arms a, is secured, to which said arms are pivotally connected the guiding-arms a. The distance or space 8, Figs.

3 and 6, between these is less than half the length of the shuttle C, so that in whatever position the shuttle may be on the surface f f of the race one or more of the arms a will -lie over the body of the shuttle to retain it on the race. These arms a are independently mounted and they may be manipulated separately by the operator to throw them up out of the way, as shown in full lines in 1. Their position both up and down is 1imited by suitable stops, as will be hereinafter described, and when down, as shown in dotted lines in Fig. 1 and full lines of Fig. 2, the inner ends are in position to properly confine the shuttle should it attempt to jump from the race, without, however, interfering with the warp-threads in any way whatever.

In order to enable all manipulations to be performed by the operator by hand without any danger of injury, the guides are made in two parts-Win, the stationary part c and the rotating part a, with the arms 0 and c, said arms a being pivoted at cl. The rotating por- 9o tions may be turned upfrom their normal position (shown in Fig. 2 in full lines and in Fig.

1 in dotted lines) by simply applying slight pressure to them with the finger, so that they assume the position shown in Fig. 1 in full 5 lines. The arms are so balanced that they return to their normal position of their own accord directly the loom is set in motion.

Should it therefore so happen that in consequence of an oversight or carelessness on the part of the attendant any one of the guidingarlns has not been turned down again after the attendant has performed his duty no damage can result from the omission, since as soon as the lay is put in motion the arm will automatically descend.

The fixed parts 6 are fitted with projections t, and the pivoted parts a have corresponding notches i to engage said projections, The projections 75 limit the rotary movement of the pivoted parts in both directions.

Referring to Figs. 4 to 6, the same letters are applied to corresponding parts. The projections t and the corresponding notches of the pivoted parts a prevent the latter from rotating too far in the direction of the arrow a*, Fig. 4.

of the pivoted parts in the direction of the arrow 13*, Fig. 4-

Having now particularly described and ascertained the nature of the said invention and in What manner the same is to be performed, I declare that what I claim is- 1. In combination with the lay and its race The lugs it limit the revolution a series of independently-pivoted guards each guard having its lower edge of a general convex contour and arranged to be above the plane of the warps and to prevent theshuttle from moving from the race, substantially as described.

In witness whereof I have hereunto set my hand, in presence of two witnesses, this 31st day of January, A. D. 1896.
